Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSuUser(Contributed Perl DocPerl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr(3pm)

NAME

       Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument "substr" instead of writing "substr($foo, 2, 6) = $bar".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Conway discourages the use of "substr()" as an lvalue, instead recommending that the 4-argument version of "substr()" be used instead.

	   substr($something, 1, 2) = $newvalue;     # not ok
	   substr($something, 1, 2, $newvalue);      # ok

       The four-argument form of "substr()" was introduced in Perl 5.005.  This policy does not report violations on code which explicitly
       specifies an earlier version of Perl (e.g. "use 5.004;").

CONFIGURATION

       This Policy is not configurable except for the standard options.

SEE ALSO

       "substr" in perlfunc (or "perldoc -f substr").

       "4th argument to substr" in perl5005delta
